Stakeholders Feedback on T/E Stakeholders Feedback on T/E IssuesIssues

� Uncertainty with national pesticide T/E issues� Desire to have input on any mitigation

measures to ensure they are reasonable� Want to utilize non-regulatory approaches

when they are shown to be effective � Want to ensure that EPA is operating with

most accurate data available

North Dakota’s Endangered North Dakota’s Endangered Species PlanSpecies Plan

North Dakota’s Goals for North Dakota’s Goals for Endangered Species Endangered Species Protection Protection

PlanPlan• Protect Endangered Species without causing

an unreasonable burden to agriculture producers

• To supply EPA with state specific information to use in risk assessments

• To provide a platform for stakeholders to offer input and recommendations

• To help plan and implement mitigation and management plans, including Endangered Species Protection Bulletin (Bulletins)

Data inputData input� Many different sources have data� State agency data often ignored or not

asked for during risk assessments� There are no procedures currently in place

for states to offer data to be used for risk assessments or bulletin development

State Information useful for a State Information useful for a Registration ReviewRegistration Review

� State water quality monitoring data� Pesticide use data� Cropping information� Endangered species locations� Local soil types

State Information useful for State Information useful for Bulletin DevelopmentBulletin Development

� Technological, social and economic feasibility of restrictions� State can work with growers to gain buy

in and compliance with bulletins or other restrictions� Review bulletins and associated maps for

accuracy

The FutureThe FuturePossible state program- map based with

voluntary recommendations, work with local FWS

SummarySummary� States have information that could be

useful during decision making� Bulletins can have a high economic

impact, agencies should examine all data available
